Highly recommended.
This motor has been bulletproof for me so far. After 300+ flights of running this motor at full throttle every second of every flight, I am convinced it is underrated. I run mine on 4S with an 8x8 prop and with a wattmeter attached it was drawing 54amps and outputting 850 watts, which is basically right at the limit of what this motor is specified to do. Being conservative in my estimation, this motor has had at least 20 hours of full throttle time and feels no different than it did when I first tried it out. Highly recommended.

Perfect motor for a 50mm wingspan pylon racer like their Shoestring
This motor on an E-Flite Shoestring E15, with an 8x8e prop, and 4S 2800mah lipo is just insane. One of the fastest planes I've ever flown, I'm not kidding. Well over 100 miles per hour in a straight line. Loving it!

Great Motor
Great little motor. This is a replacement for the one I crashed. Strong and reliable until you noise dive into the ground. If I ever damage this one I would buy another.

Turbo 25
Love this motor mounted like a glove in my turbo timber! Combined with 11x7 prop and 3000 mAH 4s 60c battery and 85 aerostar esc pulling 91 amp burst current! The thing is a bullet I know I must go to smaller prop or will tear heart and liver out of this little motor lol!
